text: The Enriched Xenon Observatory-200 experiment uses xenon both as source and detector. The experiment is located in New Mexico (US) and uses a time-projection chamber (TPC) for three-dimensional spatial and temporal resolution of the electron track depositions. The EXO-200 experiment yielded a lifetime limit of  years (90% C.L.). When translated to effective Majorana mass, this is a limit of the same order as that obtained by GERDA I and II.
